On another egroup that I belong to (hpslash), someone who was at the 
Edinburgh Book Festival posted a message about some of the things JKR 
said about the books, and I thought you might be rather interested...

<<Oh you won't believe this cos it's taken me so long to tell you all 
but I actually met JK Rowling about a month ago. I went up to 
Edinburgh for the book festival and went to one of her readings!  
Luckily I wasn't the only semi grown up there otherwise it could've 
been quite embarrassing... here's some possible spoilers that she let 
slip...

 - Mrs Figg is a squib.  Godric's Hollow (where is that again?) is 
gonna be very important as is Snape and the whole thing with Harry's 
eyes!  She says Snape could still turn out to be either bad or good 
but she's not telling us which.  The really big death comes in book 
five.  She has already written the very final chapter of the whole 
series.  The Dark Mark chapter in the GoF was a killer for her to 
write - she rewrote it about 9 times and ended up thinking she'd 
never be able to finish it.>>

Isn't that interesting?  A really big death in 5 - Lupin?  (please 
no!) Ron?  Dumbledore?  Sirius?  I wonder whether whoever it is will 
hang around as a ghost (tying this in with our discussion of the 
week).  

And what is there to know about Godric's Hollow except that the 
Potters used to live there?  Godric Gryffindor ... could Harry be a 
descendent?  

Could Mrs Figg be the person who manages to do magic in desperate 
circumstances?  And what about Arabella Figg ... this would suggest 
that Mrs Figg is a relative rather than being Arabella, though I 
suppose Dumbledore might have a Squib in his League for his own 
reasons.  

And just to let you know, I've now completed 'A Second Chance,' and 
you can read it at http://www.fanfiction.net if you do a search for 
the title.
